Guarded infusor needle and infusor locking system
First Claim
1. A surgical device, comprising:
- a penetrator configured to pierce a membrane of a patient; and
a guard positionable to selectively permit and prohibit guarding of the penetrator from piercing the membrane, the guard comprising;
a shield member movable along a longitudinal axis between a first position covering the penetrator and a second position uncovering the penetrator, the shield member comprising a stop member;
a locking member configured to contact the stop member to prohibit the shield member from moving from the first position to the second position; and
an unlocking member surrounding a portion of the shield member and configured to move along the longitudinal axis to move the locking member out of contact with the stop member to permit the shield member to move from the first position to the second position.

13. A surgical device, comprising:
-
a tube comprising a penetrator and a guard positionable to permit and prohibit the penetrator from piercing a peritoneum of a patient;
a handle connected to the tube, the handle defining a void;
a guard tube disposed in the void and connected to the guard such that the guard and guard tube are selectively movable along a longitudinal axis from a covering position in which the guard covers the penetrator to an uncovering position in which the guard uncovers the penetrator;
a locking tube disposed on the guard tube;
a locking member disposed in the void and movable between a locked position in which the locking member contacts the locking tube to prevent the guard from uncovering the penetrator and an unlocked position in which the locking member is out of contact with the locking tube to permit the guard to uncover the penetrator; and
an unlocking member surrounding the guard tube and movable along the longitudinal axis between an unarmed position in which the unlocking member permits the locking member to contact the locking tube to prevent the guard from uncovering the penetrator and an armed position in which the unlocking member moves the locking member out of contact with the locking tube to permit the guard to uncover the penetrator. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A method of using a surgical device including a penetrator configured to pierce a membrane of a patient and a guard positionable to permit and to prohibit the penetrator from piercing the membrane, the guard including a shield member movable along a longitudinal axis between a first position covering the penetrator and a second position uncovering the penetrator, the shield member including a stop member, the guard including a locking member configured to contact the stop member to prohibit the shield member from moving from the first position to the second position, and the guard including an unlocking member surrounding a portion of the shield member and configured to move along the longitudinal axis to move the locking member out of contact with the stop member to permit the shield member to move from the first position to the second position, the method comprising:
-
moving the unlocking member along the longitudinal axis to uncover the penetrator; and
piercing the membrane with the uncovered penetrator.
-
-
21. The method according to claim 21, wherein piercing the membrane comprises piercing the membrane with one of a needle and a trocar.
-
22. A method of using a surgical device, comprising:
-
moving an unlocking device in a longitudinal direction such that the unlocking device moves a locking device out of contact with a stop member disposed on a shield member; and
moving the shield member along the longitudinal axis to uncover a penetrator to pierce a membrane of a patient. - View Dependent Claims (23, 24, 25)
